JOHN BRAISLIN, OF BURLINGTON, NEV JERSEY.

BMPROVEIVIENT IN TILE-MACHINES.

' Spccilication forming part of Letters Patent No. 1ML/5@ dated November il, 1863.

To all whom it may concern.-

Be it:known that I, JOHN BRAISLIN, of Bur-` lington, Burlington countyNew Jersey, have invented ycertain Improvements in Tile Machinery; and I do hereby declare the following to be a full, clear, and exact description ofthe same, reference being had to theaccompanying drawings, and to the. letters of reference marked thereon.

My invention consists of certain improve- I ments, fully described hereinafter, in lnachinery for making draining and other tiles.

In order to enable others skilled in this class of machinery to make and use my invention, I will now proceed to describeits construction and operation.

Ou reference to the accompanying drawings, which form a part of this specification, Figure l is a vertical section of my improved tilemachine; Fig. 2, a front view, looking in the direction of the arrow, Fig. 1; and Fig. 3, a sectional plan on the line l 2, Fig. l.

Similar letters refer to similar parts throughout the several views.

A represents the base-plate of the machine, on which is erected a box, B, and at the front of the latter is the mixing trough or reservoir C.

To the base-plate are secured the two frames D and D, one being situated on each side of the box B and mixing-trough C, and in a crossbar, E, secured'to the two frames, turns the upper end of the shaft F, thelower end of the latter turning in a step, G, secured to the bottom of the trough C. Above the cross-bars E the shaft F is cranked,and the cranked portion e ofthe shaft is embraced by one end of the connecting-rod H, the opposite end of which is jointed to the upper arm of the lever I, the latter having its fulcrum on a pin, J, secured to or turning in the opposite frames D and D. The lower arm of the lever I is connected by a rod, K, to a projection, a, Fig. 3, on the cross-head L, which is arranged to slide in guides e', secured to the inside and opposite sides of the box B, the cross-head being secured by a bar, f, to theplungcr M, which fits snugly, but so as to slide freely between the opposite sides of the box B and between the under side of the mixing-trough O and upper surface of the base-plate A.

The shaft F, at a point within the trough, is provided withl several arms, i i, each havinga number of projections or spikes, and near its lower end the shaft is provided with an arm, j, havingA at its end a plate, k, so arranged that as the shaft revolves the said plate will move directly above an opening, m, which forms the communication between the mixing-trough C and the space N, in which the plunger M operates.

In front of the machine, and covering the space N, is the forming-plate P, in which are three openings, u,` and into each opening proljects a short cylindrical pin, q, which forms the internal diameter of the tiles manufactured by the machine, the external form being 5determined bythat of the openings a. The pins q are secured to a bar attached to the back of the plate P, and this bar is so formed that it shall present no obstruction to the free passage of the clay through the spaces between the pins 1 and edges of the openings a.

At the rear of the forming-plate P, and between the latter and :the mixing-reservoir, is an opening, w, large enough for the admission of a mans hand into the space N, this opening being closed by a block, y, secured to or forming a part of the bar Q, which is hinged at one` end to the portion of the machine which projects beyond the mixing-reservoir, the bar to be secured at the opposite end by any suitable fastening. In the present instance the shaft is driven by horse-power, the lever R, to which the horse is harnessed,being secured to the top of the shaft. rlhe latter, however, may be driven by belts or any suitable system of gearing.

The shaft F having been set in motion, the wet clay in the reservoir will be thoroughly mixed by the revolving spiked arms it, While the plate '7c is the means of causing a portion of this wet clay to pass through the opening m into the space N every time the said plate passes above the said opening. In the meantime a reciprocating motion is imparted to the portion e of the shaft F, the rod H, lever I, and rod K. As the plunger M advances it pushes before it the clay which has passed from the mixing-reservoir through the opening m and into the space N. On the continued advance of the plunger it closes the opening m, through which no more clay can pass until the plunger retreats. There is now in advance of the plunger a sufficient quantity of clay cut plunger through the medium of the cranked 0H from the supply in the mixing-reservoir for the plunger during the completion of its forward movement to force through the open` ings a in the plate P, and thereby convert the clay into the desired tiles.v As the plunger returns and the opening m is exposed another supply of clay is passed into the space N to be converted into tiles during therepetition of a forward movement of the plunger. When there is a stone or any other obstruction at the rear of the plate P to prevent the free passage of the clay throughthe said plate, the bar Q, with its block y, is raised, so as to permitan and remove the obstruction. As the continuous tubes of clay pass from the plate P they take their course over a series of rollers, which are common to other tile-machines, the tubes being cut to the desired lengths and subsequently dried and baked..

Although my improved machine has been illustrated-as applied to the forming of tubular draining-tiles, it will be evident that it may be appliedto the formation of other tiles, the shape of which must be determined by that of the openings in the plate P.

I wish it to be understood that I do not desire to claim of itself the forming-plate P, inasmuch as similar plates, have been used in Y attendant to insert his hand into the space Nl other tile-machines; nor do I desire to claim separately the mixing-reservoir C with its spiked arms; but

I claim as my invention and desireto secure by Letters Patent- `1. The reciprocating plunger M, space N, and forming-plate P, in combination with a mixing-reservoir and the opening m at the -bottom of the same, the whole being arranged and operating substantially as and for the purpose herein set forth. Y Y

- 2. The mixing-reservoir C and vertical shaft F, with its plate k, in combination with lthe said opening m.

3. Thevertical cranked shaft F, rod H, lever I, rod K, and plunger M, the whole being arranged for joint action, substantially as set forth. y j

4. The opening w at the'rear of the plate P, in combination with the bar Q and block y or other equivalent movable cover for the said opening. f i

In testimony whereof I have signed my name to this specication in the presence of two subscribing witnesses.

JOHN BRAISLIN.
